Back in the UK I have used a type 2 sound level meter to take a sample measurement of the noise to see if we did in fact have an issue. Luckily we didn't, as the noise peaked well below the 1st action level. (Even though no further action was needed the results still need to be recorded).
Had there been an issue, I would have handed over to an occupational hygienist to carry out some more in depth monitoring, possibly using a dosimeter, to see what noise and frequency levels were present.
We recently conducted 5 yearly noise survey, forklift operator and a reach truck operator were fitted with dose meters and noise levels was well below 85db
Hi Michael
yes we use dosimeters to take inhouse sample measurements inside our mobile plant, focusing on older plant first to see if we have any issues - cabs requiring additional baffles, maintenance etc.
The print outs are shared with the operators and noise levels have been well below 85 db.
Useful exercise to undertake.
In the past we have also used the relatively cheap clip on dosemeter to see if we could identify an issue for one of our operators when his health monitoring identified a decrease in hearing from the previous year, it lit up red when 85db was exceeded and he monitored it and reported back. Turned out his radio was the issue, he had preferred to turned it up until then. It was a good learning for everyone.
Also would hand over to an occupational hygienist for more indepth monitoring if issues are identified that additional investigation, insulation modifications or maintenance did not resolve.
